避震器能吸收路面凹凸所帶來的衝擊，而廣泛的運用在汽機車等車輛中。避震器可分為正插式(upright)避震器與倒插式(inverted)避震器二種。其中，倒插式避震器是以固定於外筒上的二個軸承支承減震筒。倒插式避震器具有良好的抗衝擊能力以及穩定性，而深受車友的喜愛。 The shock absorber absorbs the impact of uneven road surface and is widely used in vehicles such as steam locomotives. Shock absorbers can be divided into two types: upright shock absorbers and inverted shock absorbers. Among them, the inverted insert shock absorber is a shock absorber cylinder supported by two bearings fixed to the outer cylinder. The inverted shock absorber has good impact resistance and stability, and is very popular among riders.
然而，在長久的使用之下，倒插式避震器中的減震筒會對軸承產生不均勻的磨耗受損，而使減震筒與軸承之間於單側的間隙變大。在車輛在行駛時，減震筒與軸承之間的間隙會導致倒插式避震器發出異音，進而降低行車的品質。 However, under long-term use, the damper cylinder in the inverted-type shock absorber can cause uneven wear damage to the bearing, and the gap between the damper cylinder and the bearing on one side becomes large. When the vehicle is running, the gap between the damper cylinder and the bearing causes the inverted shock absorber to emit an abnormal sound, thereby reducing the quality of the driving.
因此，本發明的目的即在提供一種倒插式避震器，能避免減震筒對軸承產生不均勻的磨耗受損。 Accordingly, it is an object of the present invention to provide an inverted insert shock absorber that avoids uneven wear damage to the bearing by the damper cylinder.

以下根據第1圖至第3圖，而說明本發明的實施方式。該說明並非為限制本發明的實施方式，而為本發明之實施例的一種。 Hereinafter, embodiments of the present invention will be described with reference to Figs. 1 to 3 . This description is not intended to limit the embodiments of the invention, but is an embodiment of the invention.
如第1圖至第2圖所示，依據本發明的第一實施例的一倒插式避震裝置100，包含：一外筒1；一減震筒2，具有一減震筒筒體21以及一活塞桿22，以減震筒筒體21的外表面對向外筒1的內表面之方式而同軸套設於外筒1中，活塞桿22的一端固定於外筒1的下端，活塞桿22的另一端穿入於減震筒筒體21內；至少三個軸承3a、3b、3c，設置於外筒1的內表面及減震筒筒體21的外表面之間，且為固定於外筒1的內表面的一避震器伸縮方向D上的不同位置而支承減震筒筒體21的外表面，使減震筒筒體21相對於外筒1沿避震器伸縮方向D為可滑移；以 及一O形環4，設置於外筒1的內表面及減震筒筒體21的外表面之間而緊密套置減震筒筒體21的外表面，且在避震器伸縮方向D的兩側受至少三個軸承3a、3b、3c的其中二個軸承3a、3b夾置，O形環4對減震筒筒體21提供相對於外筒1徑向限位的穩定力以穩定外筒1與減震筒筒體21之間的滑移。 As shown in FIGS. 1 to 2, a reverse insertion type shock absorber 100 according to a first embodiment of the present invention includes: an outer cylinder 1; a shock absorbing cylinder 2 having a damper cylinder 21 And a piston rod 22 coaxially sleeved in the outer cylinder 1 so that the outer surface of the damper cylinder 21 faces the inner surface of the outer cylinder 1, and one end of the piston rod 22 is fixed to the lower end of the outer cylinder 1, the piston The other end of the rod 22 penetrates into the damper cylinder 21; at least three bearings 3a, 3b, 3c are disposed between the inner surface of the outer cylinder 1 and the outer surface of the damper cylinder 21, and are fixed The outer surface of the damper cylinder 21 is supported at a different position on the inner surface of the outer cylinder 1 in a shock absorber expansion and contraction direction D, so that the damper cylinder 21 is along the outer cylinder 1 along the expansion and contraction direction D of the shock absorber. Slidable; And an O-ring 4 disposed between the inner surface of the outer cylinder 1 and the outer surface of the damper cylinder 21 to tightly enclose the outer surface of the damper cylinder 21 and in the direction of the expansion and contraction of the shock absorber D The two sides are sandwiched by two of the bearings 3a, 3b of the at least three bearings 3a, 3b, 3c, and the O-ring 4 provides a damping force to the damper cylinder 21 with respect to the radial direction of the outer cylinder 1 to stabilize the outside. Slip between the barrel 1 and the damper cylinder 21.
其中，倒插式避震裝置100為單筒式(mono cylinder)的倒插避震器，一般用於汽車之避震。設置於外筒1及減震筒筒體21之間的三個軸承3a、3b、3c皆為自潤軸承，以在不給油的情況下保持低摩擦的特性。而在其他實施例中，軸承3a、3b、3c可以選用其他的軸向滑動軸承。O形環4對減震筒筒體21提供徑向限位的穩定力為指向外筒1的中心軸，以維持減震筒筒體21位於外筒1的正中央。 Wherein, the inverted insertion type shock absorber 100 is a single cylinder type (mono Cylinders are used for shock absorbers in cars. The three bearings 3a, 3b, and 3c disposed between the outer cylinder 1 and the damper cylinder 21 are self-lubricating bearings to maintain low friction characteristics without oil supply. In other embodiments, the bearings 3a, 3b, 3c may be other axial plain bearings. The stabilizing force by which the O-ring 4 provides radial restriction to the damper cylinder 21 is directed to the central axis of the outer cylinder 1 to maintain the damper cylinder 21 in the center of the outer cylinder 1.
在減震筒筒體21對軸承3a、3b、3c的單側施加不均勻推力時，O形環4能提供反向於不均勻推力的穩定力以抵銷不均勻推力，而能避免減震筒2對軸承3a、3b、3c產生不均勻的磨耗受損，進而延長倒插式避震裝置100的使用壽命。 When the damper cylinder 21 applies uneven thrust to one side of the bearings 3a, 3b, 3c, the O-ring 4 can provide a stabilizing force against the uneven thrust to offset the uneven thrust, and can avoid shock absorption. The cylinder 2 causes uneven wear damage to the bearings 3a, 3b, 3c, thereby prolonging the service life of the reverse insertion type shock absorber 100.
如第2圖所示，依據本發明的第一實施例的倒插式避震裝置100，夾置O形環4的其中二個軸承3a、3b是設置靠近於外筒1的上端。而在其他實施例中，夾置O形環4的其中二個軸承也可以是設置靠近於外筒1的下端或其他位置，以對於減震筒筒體21的不同位置提供穩定力。 As shown in Fig. 2, according to the reverse insertion type shock absorbing apparatus 100 of the first embodiment of the present invention, two of the bearings 3a, 3b sandwiching the O-ring 4 are disposed adjacent to the upper end of the outer cylinder 1. In other embodiments, the two bearings sandwiching the O-ring 4 may also be disposed adjacent to the lower end or other position of the outer cylinder 1 to provide a stabilizing force for different positions of the damper cylinder 21.
其中，位在上方的軸承3a的長度L1與位在下方的軸承3b的長度L2為相異。相較於習知的倒插式避震器，於本實施例的外筒1的內表面額外固定設置長度較短的軸承3b，而能在不實質影響原有之軸承3a、3c與減震筒筒體21之間的摩擦力的情形下，限制住O形環4的位置。也就是，軸承3b的長度L2小於軸承 3a的長度L1。軸承3b輔助軸承3a支承減震筒筒體21，而加強穩定減震筒筒體21的效果。 Among them, the length L1 of the bearing 3a positioned above and the length L2 of the bearing 3b positioned below are different. Compared with the conventional inverted shock absorber, the bearing 3b having a short length is additionally fixed on the inner surface of the outer cylinder 1 of the present embodiment, and the original bearing 3a, 3c and the shock absorbing can be not substantially affected. In the case of the friction between the cylindrical bodies 21, the position of the O-ring 4 is restricted. That is, the length L2 of the bearing 3b is smaller than that of the bearing The length of 3a is L1. The bearing 3b auxiliary bearing 3a supports the damper cylinder 21, and the effect of stabilizing the damper cylinder 21 is enhanced.
如第3圖所示，依據本發明的第二實施例的倒插式避震裝置100a，整體相似於第一實施例的倒插式避震裝置100。其差異在於：在第二實施例中，夾置O形環4的二個軸承3a、3b的長度L1、L2為相同。也就是，第二實施例的軸承3b之長度L2大於第一實施例的軸承3b之長度L2。藉此，在第二實施例中，能以統一的規格設置軸承3a、3b，以降低生產成本。除此之外，相較於第一實施例，能對減震筒筒體21提供較佳的穩定效果。 As shown in Fig. 3, the reverse insertion type shock absorbing apparatus 100a according to the second embodiment of the present invention is entirely similar to the reverse insertion type suspension apparatus 100 of the first embodiment. The difference is that in the second embodiment, the lengths L1, L2 of the two bearings 3a, 3b sandwiching the O-ring 4 are the same. That is, the length L2 of the bearing 3b of the second embodiment is larger than the length L2 of the bearing 3b of the first embodiment. Thereby, in the second embodiment, the bearings 3a, 3b can be provided in a uniform specification to reduce the production cost. In addition to this, the damping cylinder body 21 can be provided with a better stabilizing effect than the first embodiment.
以上之敘述以及說明僅為本發明之較佳實施例之說明，對於此項技術具有通常知識者當可依據以下所界定申請專利範圍以及上述之說明而作其他之修改，惟此些修改仍應是為本發明之發明精神而在本發明之權利範圍中。 The above description and description are only illustrative of the preferred embodiments of the present invention, and those of ordinary skill in the art can make other modifications in accordance with the scope of the invention as defined below and the description above, but such modifications should still be It is within the scope of the invention to the invention of the invention.
